How much do you want to disassemble? Do you just want to take the bolt out, or completely tear it down. Unless you are very familiar with the 550, it's not an easy job to tear down and assemble again.

 

I don't want to do anything more with it than you would on a normal cleaning. I just bought it and wanted to make sure everything was ok before shooting it. I ran a couple of patches through it and they came out clean on the first pass.

 

You have the stock off. 2 Pull the trigger to release the striker. Unscrew the end cap, be careful, because springs will come out. Not so much tension that you can't control them, but be careful and do not lose the collar at the front of the bolt spring. 3. Move the bolt all the way to the rear, until the bolt handle aligns with the opening at the end of it's track, and remove the bolt handle, to right. 4. Use a small tool, small screwdriver etc., to push the bolt toward the rear, remove the bolt from the rear.
That should get you to where you can see clearly through the bore, and it reassembles the same way in reverse.

cool, thanks!

 

You are very welcome.

 

On the bottom is a screw that holds the sear spring. If you take it out, the sear will drop, and the screw will not go right back in. Most of these rifles have been messed up when people try to force that screw back in without moving the sear, so that it sits correctly. Get some teardown instructions before taking it apart.

 

I took it to the range and ran 250 rounds through it today. What a great rifle! nice tight groups and dead on at 100yds. Took it home and disassembled/ cleaned it. I didn't remove the sear screw, I just took the bolt out and cleaned the chamber and bolt assembly. Getting it back together was a little tricky, from getting the bolt to to over the levers at the bottom of the receiver to getting the firing pin to drop all the way in took a few tries, but its back in one piece and everything seems to move the way it was designed.

Thanks for the help!
